They nailed it. 4 games in, yeah you'd have to say that at this point, Nintendo has beaten 'new' old 2D throwback Mario into the ground...and now that I heard the guys talk about the wah-wahs on the Bombcast, I can't -not- fixate on how annoying it is - thanks for that ;).... but this isn't just a cash-in. The only thing that's a little bit tired is the aesthetic. Game-wise, I see evolution. Level design is great. Worlds are highly replayable. Love the new suits. Love the return of the ridiculous baby Yoshi. There's easily 59 dollars worth of game here. If you don't enjoy this game, it's just because you're no longer, or never were a platformer guy.
Not loving the wah-wahs, or the fact there's so much recycled music. Also not loving the implementation of the Gamepad screen (it just mirrors what's on the TV) but loving everything else.
